Which amendment ensures that only voluntary statements may be admissible in court?

The correct answer is rooted in the protections provided by the 14th Amendment. This amendment contains the Due Process Clause, which requires that all legal procedures be fair and just. This includes the requirement that statements made by a defendant must be voluntary in order to be admissible in court. Statements obtained through coercion, intimidation, or undue pressure could violate a person’s due process rights, thus rendering them inadmissible.

The other amendments listed have distinct protections. For instance, the 5th Amendment primarily addresses the right against self-incrimination, ensuring that individuals cannot be compelled to testify against themselves. The 6th Amendment focuses on the rights related to criminal prosecutions, such as the right to counsel and a fair trial. Lastly, the 8th Amendment deals with prohibitions against cruel and unusual punishment and excessive bail. While these amendments are critical in the context of criminal justice and individual rights, they do not specifically address the issue of voluntary statements and their admissibility in court as the 14th Amendment does.
